LUBBICATING-FILTER FOR ENGINES.

Specification of Letters Patent.

Patented. July 2151908.

Application filed April 1, 1907. Serial No. 365,909.

the lubricating oil is splashed by the crank so as to lubricate thevarious parts .of the mechanism against and about, which the oil isthrown.

The nature of the invention will be understood fromthe accompanyingdrawings and the following descri tion and claims: I

In the drawings igure 1 is a central vertical longitudinal section ofthe engine. Fig. 2 is a transverse section of a part thereof on the line22 of Fig. 1.

In detail upon a suitable base 10 a casing 11 is mounted forming achamber in which the crank shaft 12 is transversely mounted. This shaftis actuated by a connecting rod 13 which is pivoted to the crosshead 14that is reciprocated by the piston rod 15. Beneath the crank shaft 12-the bottom of the casing 11 is depressed to form an oil recepta thelubricatin oil cannotescape, and therethe dirt or grit of any nature.

The bottom of the casing or chamber slopes downward rearwardly from thecrank end of the guides 26 to the lower part of said chamber under thecrank shaft 17. The oil flowing out of the crank end of the guidesection 26 runs down this slope.

My invention consists in placing transversely across the path of thereturning lubricating oil a filter whereby the lubricating oil will bepurified and separated from consists of two vertical perforated plates20 and. 21 and a cap plate 22 held upon said perfoiated plates by bolts23 that extend.

through said cap and screw into the bottom of the casing 11. Thesethree'plates, with the bottom of the casing form a chamber that containspacking 24 of some filtering material. As the lubricating oil returnsdown the sloping bottom of the casing 11 it must pass through thisfilter and as it does so, the filtering material'will cleanse it. Avalve controlled drain pipe 25 leads from the steam bottom of the.casing 11 forintirely draining the lubricating oil wheneverilti is isdesired. What I-claim as my invention and desire to secure by LettersPatent is:

The combination with a machine having an inclined bottom, and means forapplying lubricating oilto said machine sothat it will flow from theparts of the machinery lubricated down said inclined bottom, ofa filterextending across the path of the lubricating oil, substantially as setforth.

In witness whereof, I have hereunto afiixed my signature in the presenceof the witnesses herein named.
